Definitions

  • the present invention relates to a ventilation device, of the type comprising a housing which has an air inlet opening and an air outlet opening and in which the active elements of the ventilation device are mounted, said housing being intended to be mounted, in service, in a correspondingly shaped opening provided in a support plate, a nozzle placed in correspondence with one of the two air openings of the housing and a flexible pipe, one end of which is connected to the nozzle and the other end of which is connected, in service, to an external conduit.
  • the present invention applies in particular to ventilation devices such as filtering groups or extractor hoods, which are usually installed in kitchens, above stoves or hobs, for extracting vapors and / or the odors given off by cooking and to evacuate them outside.
  • ventilation devices such as filtering groups or extractor hoods, which are usually installed in kitchens, above stoves or hobs, for extracting vapors and / or the odors given off by cooking and to evacuate them outside.
  • the invention can also be applied to ventilation devices such as air conditioning devices.
  • the nozzle is generally rigidly fixed to the housing around its air outlet opening. Since the flexible pipe connecting the nozzle to the external conduit must in most cases be connected to said nozzle and to said external conduit before the housing is engaged in the opening provided in the support plate, it follows that generally provide a flexible hose whose length is significantly greater than that which, in service, would be strictly necessary to connect the nozzle to the outside duct. This results in an additional cost due to the excess length of the flexible hose. In addition, when the housing is engaged in the opening provided in the support surface, due to its excess length, the flexible pipe forms elbows which not only hamper the positioning of the housing in the housing reserved for it, but still cause, in service, pressure losses which affect the proper functioning and performance of the ventilation device.
  • the present invention therefore aims to provide a ventilation device which can be simply and economically connected to an external duct, and in which the pressure losses in the flexible pipe are greatly reduced.
  • the ventilation device of the present invention is characterized in that it further comprises a support to which the nozzle is fixed and which is itself fixed, in service, to said support plate or to an element which is integral with it, said support having a shape and / or dimensions such that, after the housing has been engaged in the opening of the support plate, the nozzle closely surrounds the corresponding air opening of the housing.
  • Figure 1 is a perspective view showing a first embodiment of the invention applied to a filter unit, the housing of the filter unit being shown separate from the nozzle and the discharge pipe.
  • Figure 2 is a vertical sectional view along line II-II of Figure 1.
  • Figure 3 is a view similar to Figure 2 after engagement of the filter unit housing in the opening of the support plate.
  • Figure 4 is a view similar to Figure 3 showing the invention applied to a drawer hood.
  • Figures 5 and 6 are views similar to Figures 2 and 3, respectively, showing an alternative embodiment of the present invention.
  • FIG 1 there is shown a filter unit 1 of known type, the housing 2 is intended to be engaged and mounted in the opening 3 of a support plate 4 constituting for example a part of the lower frame 5 of a hood 6.
  • the hood 6 can for example be located above a stove or a hob.
  • the housing 2 can contain, in a known manner, a suction fan and an air filter intended to retain the dust and greasy vapors contained in the sucked air.
  • the lower face 7 of the housing 2 is widely open to form an air inlet opening (not shown), while its upper face 8 has an air outlet opening 9, for example, of rectangular shape.
  • the nozzle 12 is fixed to a support 14 which can itself be fixed to the support plate 4 or to another part of the frame 5 or of the hood 6, or even directly on the wall to which is fixed the hood 6.
  • the support 14 is preferably fixed to the support plate 4.
  • the support 14 may be constituted by a folded sheet having, in profile view, roughly the shape of a bracket, the branch 14a of which is fixed, at one end, to the support plate 4 in the region of the opening 3 thereof.
  • the other branch 14b of the support 14 carries the nozzle 12 and extends opposite the opening 3 of the support plate 4 at a predetermined distance therefrom, a distance which is a function of the height dimension of the housing 2
  • the branch 14b of the support 14 has an opening 14c having a shape corresponding to that of the outlet opening 9 of the housing 2.
  • the nozzle 12 surrounds the opening 14c and is fixed to the branch 14b for example by clipping, by screws, gluing, welding or any other suitable means.
  • a seal 15 for example made of a foam of elastomeric material or of plastic material resistant to heat, is fixed, for example by gluing, to the lower face of the branch 14b around the opening 14c (it is note that the seal 15 could also be fixed to the upper face 8 of the housing 2 around the outlet opening 9).
  • the sheet constituting the support 14 is folded in such a way that, in the absence of the housing 2 in the opening 3 of the support plate 4, the branch 14a, except in the region of its attachment to said plate support 4, extends in a direction making a small angle ⁇ ( ⁇ ⁇ 20 °) with the geometric axis 16 of the opening 3, the branch 14b being perpendicular to the branch 14a as shown in Figure 2.
  • the branch 14a of the support 14 comprises a part 14d folded outwards, which is engaged with one of the faces of the support plate 4 and which defines, in combination with the length of the branch 14a the distance aforementioned predetermined position in which the branch 14b is located relative to the support plate 4.
  • the folded portion 14d could be in contact with the upper face of the support plate 4, for reasons of ease of assembly, it is preferably engaged with the underside of said support plate 4 as is more particularly visible in Figures 1 and 2.
  • the branch 14a of the support 14 can be fixed to the support plate 4 for example by means of two screws 17 as shown in Figures 1 and 2.
  • the housing 2 can be held in place in the opening 3 and fixed to the support plate 4 in a known manner, for example by clipping by means of spring blades 18.
  • This fixing can be optionally supplemented by screws (not shown) engaged through holes 19 provided for this purpose in the housing 2 and screwed into the support plate 4.
  • connection of the housing 2 of the filter unit 1 to the external conduit 11 can be carried out in a simple and economical manner with a flexible pipe 13 whose length is reduced to a minimum and which has almost no bends.
  • the filter unit of Figures 1 to 3 is replaced by a drawer hood 20 of known type, the housing 2 'is largely similar to the housing 2 of the filter unit 1 described above. This is why the elements of the casing 2 ′ which are identical or which play the same role as those of the casing 2 are designated by the same reference numbers with the sign "′" and will therefore not be described again in detail.
  • the nozzle 12 and the support 14 have a shape and an arrangement similar to those described above with reference to FIGS. 1 to 3.
  • Figures 5 and 6 show an alternative embodiment in which the support 14 in the form of a square is replaced by a support 14 ′ in the form of a stirrup.
  • the two lateral branches 14′a of the support 14 ′ are fixed by their free ends to the support plate 4 in two opposite regions of the opening 3.
  • the fixing of each of the two branches 14′a can be carried out in a manner similar to that described above with regard to the branch 14a of the support 14 of FIGS. 1 to 3, for example by means of one or two screws 17.
  • the middle part 14′b of the support 14 ′ extends opposite the opening 3 of the support plate 4 at a predetermined distance therefrom, a distance which depends on the height dimension of the housing 2 and which can be defined as in the embodiment previously described by a folded part 14′d of each of the two lateral branches 14′a and by the length of these branches.
  • the middle part 14′b of the support 14 ′ has an opening 14′c which corresponds to the outlet opening 9 of the housing 2 after the latter has been completely engaged in the opening 3 of the support plate 4
  • the nozzle 12 is fixed to the middle part 14′b of the support 14 ′ so as to surround the opening 14′c.
  • the fact that the support 14 ′ is more rigid than the support 14 of FIGS.
